Content Storage Management
Content storage management (CSM) is a technique for the evolution of traditional media archive technology used by media companies and content owners to store and protect valuable file-based media assets. CSM solutions focus on active management of content and media assets regardless of format, type and source, interfaces between proprietary content source/destination devices and any format and type of commodity IT centric storage technology. These digital media files (or assets) most often contain video but in rarer cases may be still pictures or sound. A CSM system may be directed manually but is more often directed by upper-level systems, which may include media asset management (MAM), automation, or traffic. Typically, CSM systems are server-based software applications that reside between the media network, which connects the various broadcast or manipulation devices, and the storage network, which connects the nearline and archive storage tiers. The most basic function o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media (communication)
Means of communication or media are used by people to communicate and exchange information with each other as an information sender and a receiver. General information Many different materials are used in communication. Maps, for example, save tedious explanations on how to get to a destination. A means of communication is therefore a means to an end to make communication between people easier, more understandable and, above all, clearer. In everyday language, the term ''means of communication'' is often equated with the ''medium''. However, the term "medium" is used in media studies to refer to a large number of concepts, some of which do not correspond to everyday usage. Means of communication are used for communication between sender and recipient and thus for the transmission of information. Elements of communication include a communication-triggering event, sender and recipient, a ''means of communication'', a ''path of communication'' and ''contents of communication'' ...

Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Material Exchange Format
Material Exchange Format (MXF) is a container format for professional digital video and audio media defined by a set of SMPTE standards. A typical example of its use is for delivering advertisements to TV stations and tapeless archiving of broadcast TV programs. It is also used as part of the Digital Cinema Package for delivering movies to commercial theaters. Summary MXF, when used in the form of "Operational Pattern OP1A" or "OPAtom", can be used as a ''container'', ''wrapper'' or ''reference file'' format which supports a number of different streams of coded "essence", encoded in any of a variety of video and audio compression formats, together with a metadata wrapper which describes the material contained within the MXF file. Other "Operational Patterns" can contain or reference multiple materials, just like a simple timeline of a video editing program. MXF has full timecode and metadata support and is intended as a platform-agnostic stable standard for future professio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legacy Media
Old media, also called traditional media or legacy media, are the mass media institutions that dominated prior to the internet; particularly print media, film studios, music studios, advertising agencies, radio broadcasting, and television. Old media institutions are centralized and communicate with one-way technologies to a generally anonymous mass audience. They are often contrasted with new media, which are typically computer or smartphone-based media that are interactive and comparatively decentralized, enabling people to telecommunicate with one another peer-to-peer or through social media platforms, with mass use and availability through the Internet. Old media timeline The invention of the printing press in 1440 was the start of traditional media. The creation of the Internet forever changed the world of media. *1440 – invention of the movable type printing press by Johannes Gutenberg. This made mass production of print media possible; this reduced the need for mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Replication (computing)
Replication in computing refers to maintaining multiple copies of data, processes, or resources to ensure consistency across redundant components. This fundamental technique spans databases, file systems, and distributed systems, serving to improve availability, fault-tolerance, accessibility, and performance. Through replication, systems can continue operating when components fail ( failover), serve requests from geographically distributed locations, and balance load across multiple machines. The challenge lies in maintaining consistency between replicas while managing the fundamental tradeoffs between data consistency, system availability, and network partition tolerance – constraints known as the CAP theorem. Terminology Replication in computing can refer to: * ''Data replication'', where the same data is stored on multiple storage devices * ''Computation replication'', where the same computing task is executed many times. Computational tasks may be: ** ''Replicated in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Resource Management (SRM)
In computing, storage resource management (SRM) involves optimizing the efficiency and speed with which a storage area network (SAN) utilizes available drive space.SearchStorage.com Definitions. �What is storage resource management” Retrieved September 9, 2009. History Data growth averages around 50% to 100% per year and organizations face rising hardware and storage management costs. Storage professionals who face out-of-control data growth are looking at SRM to help them navigate the storage environment. SRM identifies under-utilized capacity, identifies old or non-critical data that could be moved to less expensive storage, and helps predict future capacity requirements. SRM evolved beyond quota management. it included functions such as storage area network A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block device, block-level data storage. SANs are primarily used to access Computer data storage, dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abstraction Layer
In computing, an abstraction layer or abstraction level is a way of hiding the working details of a subsystem. Examples of software models that use layers of abstraction include the OSI model for network protocols, OpenGL, and other graphics libraries, which allow the separation of concerns to facilitate interoperability and platform independence. In computer science, an abstraction layer is a generalization of a Conceptual model (computer science), conceptual model or algorithm, away from any specific implementation. These generalizations arise from broad similarities that are best encapsulated by models that express similarities present in various specific implementations. The simplification provided by a good abstraction layer allows for easy reuse by distilling a useful concept or design pattern so that situations, where it may be accurately applied, can be quickly recognized. Just composing lower-level elements into a construct doesn't count as an abstraction layer unless it s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stub File
A stub file is a computer file that appears to the user to be on disk and immediately available for use, but is actually held either in part or entirely on a different storage medium. When a stub file is accessed, device driver software intercepts the access, retrieves the data from its actual location and writes it to the file, then allows the user's access to proceed. Typically, users are unaware that the file's data is stored on a different medium, though they may experience a slight delay when accessing such a file. File stubbing, the act of creating stub files, is a Hierarchical storage management (HSM) concept. Purpose The usual purpose of stubbing files is to move data from an expensive high-speed storage device such as a computer's hard drive to lower cost storage such as a magnetic tape, or an electro-optical disk, while not requiring users to know how to use specialised storage software to retrieve the data. It also allows a system manager to enforce the use of low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hierarchical Storage Management
Hierarchical storage management (HSM), also known as tiered storage, is a Computer data storage, data storage and data management technique that automatically moves data between high-cost and low-cost data storage media, storage media. HSM systems exist because high-speed storage devices, such as solid-state drive arrays, are more expensive (per byte stored) than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the fast devices. HSM may also be used where more robust storage is available for long-term archiving, but this is slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Integrity
Data integrity is the maintenance of, and the assurance of, data accuracy and consistency over its entire Information Lifecycle Management, life-cycle. It is a critical aspect to the design, implementation, and usage of any system that stores, processes, or retrieves data. The term is broad in scope and may have widely different meanings depending on the specific context even under the same general umbrella of computing. It is at times used as a proxy term for data quality, while data validation is a prerequisite for data integrity. Definition Data integrity is the opposite of data corruption. The overall intent of any data integrity technique is the same: ensure data is recorded exactly as intended (such as a database correctly rejecting mutually exclusive possibilities). Moreover, upon later Data retrieval, retrieval, ensure the data is the same as when it was originally recorded. In short, data integrity aims to prevent unintentional changes to information. Data integrity is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...
